Also provided are methods of treating, managing, or preventing various disorders, such as cancer or an inflammatory disease.

The present application is a 371 of International Application No. PCT/US2012/054990, filed Sep. 13, 2012, which claims priority to U.S. Provisional Patent Application No. 61/534,841, filed Sep. 14, 2011, the entirety of each of which is incorporated herein by reference.

1. FIELD

Provided herein are formulations and dosage forms of cyclopropanecarboxylic acid {2-[(1S)-1-(3-ethoxy-4-methoxy-phenyl)-2-methanesulfonyl-ethyl]-3-oxo-2,3-dihydro-1H-isoindol-4-yl}-amide. Methods of using the formulations and dosage forms are also provided herein.

2. BACKGROUND

Drug substances are usually administered as part of a formulation in combination with one or more other agents that serve varied and specialized pharmaceutical functions. Dosage forms of various types may be made through selective use of pharmaceutical excipients. As pharmaceutical excipients have various functions and contribute to the pharmaceutical formulations in many different ways, e.g., solubilization, dilution, thickening, stabilization, preservation, coloring, flavoring, etc. The properties that are commonly considered when formulating an active drug substance include bioavailability, ease of manufacture, ease of administration, and stability of the dosage form. Due to the varying properties of the active drug substance to be formulated, dosage forms typically require pharmaceutical excipients that are uniquely tailored to the active drug substance in order to achieve advantageous physical and pharmaceutical properties.

Cyclopropane carboxylic acid {2-[(1S)-1-(3-ethoxy-4-methoxy-phenyl)-2-methanesulfonyl-ethyl]-3-oxo-2,3-dihydro-1H-isoindol-4-yl}-amide (“Compound A”) is a novel compound with anti-inflammatory activity in clinical development for the treatment of a variety of chronic inflammatory conditions. Pharmacologically, Compound A blocks the degradation of cyclic adenosine monophosphate (cAMP) via inhibition of the phosphodiesterase type IV (PDE4) enzyme, resulting in an increase in cAMP in PDE4-expressing cells including monocytes, T cells, and neutrophils. Enzyme assay data using purified PDE4 enzyme from U937 human monocytic cells indicate that Compound A has a PDE4 IC₅₀ of 100 nM (50 ng/mL). Compound A and methods for its synthesis are described, e.g., in U.S. Patent Publication No. 2010/0129363, the disclosure of which is hereby incorporated by reference in its entirety. Compound A may also be prepared according to the process described in U.S. Patent Publication No. 2010/0168475, the disclosure of which is hereby incorporated in its entirety.

Due to its diversified pharmacological properties, Compound A is useful in treating, preventing, and/or managing various diseases or disorders. However, Compound A is poorly soluble, thus, a need exists as to dosage forms of Compound A having advantageous physical and pharmaceutical properties.

It has been demonstrated in monkeys that delivering an amorphous solid dispersion using a capsule gave approximately 3.5 times the exposure compared to the crystalline form. A tablet formulation can disintegrate quickly, increasing the timeline for absorption. Polymers can help maintain the supersaturation, further increasing the timeline for absorption. A tablet formulation with low friability may also help decrease chipping and loss of active pharmaceutical ingredient during film coating. See, e.g., Puri V., Dantuluri A. K. and Bansal A. K, “Investigation of Atypical Dissolution Behavior of an Encapsulated Amorphous Solid Dispersion,” Journal of Pharmaceutical Sciences (2011) 100(6):2460-8.

4. DETAILED DESCRIPTION

Provided herein are pharmaceutical dosage forms of cyclopropanecarboxylic acid {2-[(1S)-1-(3-ethoxy-4-methoxy-phenyl)-2-methanesulfonyl-ethyl]-3-oxo-2,3-dihydro-1H-isoindol-4-yl}-amide (“Compound A”), or a pharmaceutically acceptable prodrug, salt, solvate, hydrate, or clathrate thereof. In some embodiments, the dosage forms are suitable for oral administration to a patient. In other embodiments, the dosage forms provided herein exhibit advantageous physical and/or pharmacological properties. Such properties include, but are not limited to, fast disintegration, low friability, ease of assay, content uniformity, flow properties for manufacture, dissolution and bioavailability, and/or stability. Also provided herein are kits comprising pharmaceutical compositions and dosage forms provided herein. Also provided herein are methods of treating, managing, and/or preventing a disease or condition, which comprises administering to a patient in need thereof a pharmaceutical composition or a dosage form provided herein.

Since it is contemplated in some embodiments that Compound A is delivered as an amorphous solid dispersion, increasing the timeframe for absorption is critical since the active pharmaceutical ingredient may become supersaturated in the gastrointestinal media. The tablet formulation can quickly disintegrate, decreasing the time it takes for the active pharmaceutical ingredient to go into solution and increasing the absorption time.

Without being limited by a particular theory, combining a drug in a polymer with a higher glass transition temperature helps to stabilize the amorphous drug in a solid dispersion, which in turn helps to inhibit crystallization. However, a large concentration of polymer is often required to stabilize the amorphous drug. Therefore, tablets manufactured using amorphous solid dispersions are generally weak, have high friabilities, and may gel upon contact with an aqueous medium due to the high concentration of the polymer. Without being limited by a particular theory, the oral dosage forms provided herein can stabilize Compound A, which is a poorly soluble compound, in an amorphous solid dispersion using a hydrophilic polymer. In one embodiment, the oral dosage form is a tablet.

In certain embodiments, the oral dosage forms provided herein comprise improved hardness and dissolution for tablets prepared using an amorphous solid dispersion. In certain embodiments, the oral dosage forms provided herein comprise tablets containing an amorphous solid dispersion of Compound A having fast disintegration and low friability. In certain embodiments, the amorphous solid dispersion comprises Compound A in a hydrophilic polymer such as hydroxypropyl methylcellulose (HMPC), polyvinylpyrrolidone (PVP), or hydroxypropyl cellulose (HPC), PVP VA64, hydroxypropyl methylcellulose acetate succinate, Eudragit polymers, polyvinylacetate, Polyox, Soluplus, or polyethylene glycol. In certain embodiments, the amorphous solid dispersion can be prepared by various methods such as lyophilization, spray drying, solvent casting, melt quenching, or hot melt extrusion. In certain embodiments, the oral dosage forms provided herein further comprise a diluent combination of different grades of microcrystalline cellulose and mannitol.

In some embodiments, because it is typical to obtain Compound A, or a pharmaceutically acceptable prodrug, salt, solvate, or clathrate thereof, at a purity of less than 100%, the formulations and dosage forms provided herein may be defined as compositions, formulations, or dosage forms that comprise Compound A, or a pharmaceutically acceptable prodrug, salt, solvate, or clathrate thereof, at an amount that provides the potency of a specified amount of 100% pure Compound A.

In certain embodiments, provided herein are anhydrous pharmaceutical compositions and dosage forms including an active ingredient, since water can facilitate the degradation of some compounds. For example, the addition of water (e.g., 5 percent) is widely accepted in the pharmaceutical arts as a means of simulating shelf-life, i.e., long-term storage in order to determine characteristics such as shelf-life or the stability of formulations over time. See, e.g., Jens T. Carstensen, Drug Stability: Principles & Practice, 2d. Ed., Marcel Dekker, NY, N.Y., 1995, pp. 379-80. In effect, water and heat accelerate decomposition. Thus, the effect of water on a formulation can be of great significance since moisture and/or humidity are commonly encountered during manufacture, handling, packaging, storage, shipment, and use of formulations.

An anhydrous pharmaceutical compositions should be prepared and stored such that the anhydrous nature is maintained. Accordingly, in some embodiments, anhydrous compositions are packaged using materials known to prevent exposure to water such that they can be included in suitable formulary kits. Examples of suitable packaging include, but are not limited to, hermetically sealed foils, plastic or the like, unit dose containers, blister packs, and strip packs.

In this regard, also provided herein is a method of preparing a solid pharmaceutical formulation including an active ingredient through admixing the active ingredient and an excipient under anhydrous or low moisture/humidity conditions, wherein the ingredients are substantially free of water. The method can further include packaging the anhydrous or non-hygroscopic solid formulation under low moisture conditions. By using such conditions, the risk of contact with water is reduced and the degradation of the active ingredient can be prevented or substantially reduced.

4.1.1. Second Active Agents

In certain embodiments, provided herein are compositions and dosage form of Compound A, or a pharmaceutically acceptable stereoisomer, prodrug, salt, solvate, or clathrate thereof, which may further comprise one or more secondary active ingredients. Certain combinations may work synergistically in the treatment of particular types diseases or disorders, and conditions and symptoms associated with such diseases or disorders. Compound A, or a pharmaceutically acceptable stereoisomer, prodrug, salt, solvate, or clathrate thereof, can also work to alleviate adverse effects associated with certain second active agents, and vice versa.

4.2. PROCESS FOR MAKING DOSAGE FORMS

Dosage forms provided herein can be prepared by any of the methods of pharmacy, but all methods include the step of bringing the active ingredient into association with the excipient, which constitutes one or more necessary ingredients. In general, the compositions are prepared by uniformly admixing (e.g., direct blend) the active ingredient with liquid excipients or finely divided solid excipients or both, and then, if necessary, shaping the product into the desired presentation (e.g., compaction such as roller-compaction). If desired, tablets can be coated by standard aqueous or non-aqueous techniques.

A dosage form provided herein can be prepared by compression or molding, optionally with one or more accessory ingredients. Compressed tablets can be prepared by compressing in a suitable machine the active ingredient in a free-flowing form such as powder or granules, optionally mixed with an excipient as above and/or a surface active or dispersing agent. Molded tablets can be made by molding in a suitable machine a mixture of the powdered compound moistened with an inert liquid diluent. Encapsulation of the dosage forms provided herein can be done using capsules of methylcellulose, calcium alginate, or gelatin.

In some embodiments, the active ingredients and excipients are directly blended and loaded into, for example, a capsule, or compressed directly into tablets. A direct-blended dosage form may be more advantageous than a compacted (e.g., roller-compacted) dosage form in certain instances, since direct-blending can reduce or eliminate the harmful health effects that may be caused by airborne particles of ingredients during the manufacture using compaction process.

Direct blend formulations may be advantageous in certain instances because they require only one blending step, that of the active and excipients, before being processed into the final dosage form, e.g., tablet or capsule. This can reduce the production of airborne particle or dust to a minimum, while roller-compaction processes may be prone to produce dust. In roller-compaction process, the compacted material is often milled into smaller particles for further processing. The milling operation can produce significant amounts of airborne particles, since the purpose for this step in manufacturing is to reduce the materials particle size. The milled material is then blended with other ingredients prior to manufacturing the final dosage form.

For certain active ingredients, in particular for a compound with a low solubility, the active ingredient's particle size is reduced to a fine powder in order to help increase the active ingredient's rate of solubilization. The increase in the rate of solubilization is often necessary for the active ingredient to be effectively absorbed in the gastrointestinal tract. However for fine powders to be directly-blended and loaded onto capsules, the excipients should preferably provide certain characteristics which render the ingredients suitable for the direct-blend process. Examples of such characteristics include, but are not limited to, acceptable flow characteristics. In one embodiment, therefore, provided herein is the use of, and compositions comprising, excipients which may provide characteristics, which render the resulting mixture suitable for direct-blend process, e.g., good flow characteristics. In certain embodiments, a dry blend tablet formulation is the preferred way of making the tablets provided herein.

4.2.1. Screening

The process for making the pharmaceutical compositions of the invention preferably includes the screening of the active ingredient and the excipient(s). In one embodiment, the active ingredient is passed through a screen having openings of about 200 microns to about 750 microns. In another embodiment, the active ingredient is passed through a screen with openings of about 200 microns to about 400 microns. In one embodiment, the active ingredient is passed through a screen having openings of about 300 to about 400 microns. Depending on the excipient(s) used, the screen openings vary. For example, disintegrants and binders are passed through openings of about 430 microns to about 750 microns, from about 600 microns to about 720 microns, or about 710 microns. Lubricants are typically passed through smaller openings, e.g., about 150 microns to about 250 microns screen. In one embodiment, the lubricant is passed through a screen opening of about 210 microns.

4.2.2. Pre-Blending

After the ingredients are screened, the excipient and active ingredient are mixed in a diffusion mixer. In one embodiment, the mixing time is from about 1 minute to about 50 minutes, from about 5 minutes to about 45 minutes, from about 10 minutes to about 40 minutes, or from about 10 minutes to about 25 minutes. In another embodiment, the mixing time is about 15 minutes.

When more than one excipient is used, the excipients may be admixed in a tumble blender for about 1 minute to about 20 minutes, or for about 5 minutes to about 10 minutes, prior to mixing with the active ingredient.

4.2.3. Roller Compaction

In one embodiment, the pre-blend may optionally be passed through a roller compactor with a hammer mill attached at the discharge of the compactor.

4.2.4. Final Blend

When a lubricant, e.g., sodium stearyl fumarate, is used, the lubricant is mixed with the pre-blend at the end of the process to complete the pharmaceutical composition. This additional mixing is from about 1 minute to about 10 minutes, or from about 3 minutes to about 5 minutes.

4.2.5. Encapsulation

The formulation mixture is then optionally encapsulated into the desired size capsule shell using, for example, a capsule filling machine or a rotary tablet press.

4.2.6. Tableting

The formulation mixture can also be tableted (e.g., via compaction, compression, or molding) into the desired size and shape tablet using, for example, a tablet press or other conventional tableting equipment and standard techniques.

4.3. KITS

5.1. FORMULATION OF COMPOUND A DOSAGE TABLET

Table 1 illustrates a batch formulation and oral dosage formulation for an amorphous solid dispersion of Compound A.

TABLE 1 Trade Name Common Name Weight Percent Tablet Formulation Ceolus KG-1000* Microcrystalline Cellulose* 10.0% Avicel PH-102 Microcrystalline Cellulose 14.3% Parteck M200 Mannitol 36.4% Ac-Di-Sol Sodium croscarmellose 5.0% Calcium stearate^(†) 1.0% Hot Melt Formulation 33.3% 100.0% Hot Melt Formulation Compound A 15.0% Methocel E3 LV Hydroxypropyl methylcellulose 85.0% 100.0% *Maximum-compactibility grade microcrystalline cellulose. ^(†)Magnesium stearate may be used in the alternative.

An amorphous solid dispersion of Compound A in HPMC was prepared as a milled hot melt extruded powder, then dry blended with the remaining excipients and carriers.

5.2. STABILITY OF FORMULATION

Accelerated stability was assessed at room temperature, 40° C./75% RH, and 50° C./80% RH. Samples were pulled for hardness testing, assay and dissolution at 1 and 3 months.

As depicted in FIG. 1, there was no decrease in hardness at room temperature over time. As depicted in FIGS. 2 and 4, in tablets with protective packaging, substantially all of the active pharmaceutical ingredient was released within 10 minutes, and there was no change in dissolution over time up to 1 year period, even under accelerated conditions. As shown in FIG. 3, substantially similar stability profile (up to 3 months) was also observed in tablets without protective packaging.

As illustrated in Table 2, although assay showed a decrease by approximately 5% for all conditions, the purity remained constant at 99.6% for all conditions.

TABLE 2 Time (Weeks) RT 40° C./75% 50° C./80%  0 108.4% 108.4% 108.4%  4 109.3% 107.9% 106.7% 12 104.1% 103.8% 103.2%

These results show that the formulations provided herein have adequate stability for clinical and other uses, which meet the desired criteria of high hardness (>70 N) and fast disintegration (<10 min). Using AI-AI packing, no change in dissolution or purity of the active pharmaceutical ingredient (“Compound A”) was observed, indicating stable formulation by hot melt extrusion.

The unique combination of excipients in the formulation helps give the tablet a low friability and fast disintegrating properties. Without limited by a particular theory, Ceolus KG-1000 may play an important role in creating the properties shown by the formulation due to its high compactibility.
